Title: Stacked sheets with page turning parts
Inventor: SEKI HAJIME
IPC: B42D3/14
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To provide stacked sheets with page turning parts for effectively and smoothly turning over a page of the stacked sheets obtained by stacking a plurality of sheets such as a book, newspaper or notebook and contributing to conservation of sheet resources. SOLUTION: Lacks such as an arc-like cut-in part 1 and a triangular cut-in part 2 are formed at substantially intermediate part and lower edge of an end edge 8 of stacked sheets such as a book obtained by stacking many sheets 4. The lacks are gradually reduced in the cut-in amounts from the top face side to the bottom face side or from the bottom face side to the top face side. When fingers are brought into contact with the lacks and slightly moved in the page turning direction, the sheets 4 are effectively turned over one by one. And, the sheets can be saved by forming the lacks.

Title: Manufacture of knob for electric appliance
Inventor: SUGANUMA SHIGERU
IPC: B29C65/18
Filed: 1979-03-29
Abstract: PURPOSE: To simply and firmly adhere a screw rod into a knob by a method wherein a heated knurled portion of the screw rod is pushed into  fitting hole, provided in a knob proper, with a diameter being a bit smaller than an outer diameter of the knurled portion, and is secured thereat.  
     CONSTITUTION: A knob proper 1, a screw rod 3, and a washer 7 are previously  prepared. A knurled portion 6 of the screw rod 3 is heated to a temperature being  higher than a melting point of plastic resins of the knob proper 1. The washer 7 is  positioned in a place, and the knurled porton 6 is then pushed into a fitting hole 2. This causes plastic resin at the surrounding of the fitting hole 2 to be molten, whereby the molten resin is stuck to the knurling. The washer 7 is positioned between the nip formed by the knob proper 1 and a flange 4. Where the knurled portion 6, which is heated to an sufficiently high temperature, is pushed into the fitting hole 2, the plastic resin is molten and flown into the spline grooves of the knurling and the highs of the knurling also bite into the plastic resin. Besides, seizure so produced connects firmly together the metal made knurled portion 6 and the plastic resin. Thus, the portion so connected can be protected from being disassembled even if a strong torsion force is applied thereon.

With the ends of external leads 5 being separated from the frame 1, the outer leads 5 may be formed in a process preceding the installation of a semiconductor chip on the head 2. With the disconnection of the ends of the leads 5 being accomplished only at the final stage of the entire process, there will be no lead deformation attributable to a force from outside or any increase in pitch errors.

Abstract: PURPOSE: To equalize the temperature distribution in the circumferential direction of a case, to equalize the deformation of the case, and to prevent the contact of a suction cover and an impeller by generating a flow in the fluid in a chamber formed by the case and the suction cover.  
     CONSTITUTION: The pressure at a through hole 9A provided in a side wall 2A of the suction cover 2 is lower than the intake pressure. Therefore the fluid in the chamber 8 between the case 1 and the suction cover 2 is sucked to a suction cover intake path 2C via the through hole 9A. While at a through hole 9B provided in an exhausting side wall of the suction cover 2, the flow of the fluid is stopped by a separating plate 2B, and the pressure rises by the amount corresponding to the hynamic pressure. Therefore, the fluid in the suction cover 2 is compressed into the chamber 8 via the through hole 9B. By the flow of said fluid, the fluid having the same temperature flows in the chamber 8, the case 1 is approximately uniformly cooled and the deformation can be equalized.

The container has a solid polymer label (10) on its underside (22) that is adjacent the container when applied, which is provided with a finite area (65) on its leading edge (25) and a finite area (66) on its trailing edge (27), by applying thereto a solvent for the polymer in each of the finite areas, the finite areas (65, 66) comprising a viscous tacky solution of the polymer in the solvent, the solidifying solution being sufficient to tack and bond the lavel (10) to container (8) during wrapping. After the label is wrapped around the container, the bond between the container and label becomes weaker as the solidifying solution hardens so that later the label (10) can be easily and cleanly stripped from the container (8) for recycling. The label can be a co-extruded plastics label having a first solid polymer layer (20) and another solid polymer layer, the finite areas (65, 66) being applied to the first solid polymer layer (20).
